3. The catalytic cracking of gas oil A follows 2nd order reaction in a conveyer moving bed reactor. Due to formation of coke independent deactivation occurs. rA=0.6(gCat.)molmindm3CA2;kd= 0.72min1. The reactor contains 20kg of catalyst moving at a rate of 10kg/min. The gas oil is fed at a rate of 50mol/min at a concentration of 0.1mol/dm3. Determine the conversion that can be achieved in this reactor. [15] 4. The catalytic hydro-desulfurization of dibenzothiophene (DBT) of diesel is as follows: Correlate the conversion of DBT with respect to axial length of a trickle bed reactor when a) the reaction is of pseudo-first order with respect to hydrogen concentration due to high concentration of DBT (1000ppm) in feed diesel, if the liquid is saturated with hydrogen; b) the reaction is of pseudo-first order with respect to the concentration of DBT as its concentration is low.

The reduction of iron ore of particle diameter of 10mm and density of 4.6gm/cm3 by pure hydrogen gas can be represented as 4H2+Fe3O44H2O+3Fe. With no water vapor present, the process follows shrinking-core model well. The first order rate constant is given by k=1.93105e12078/7,cm/s. Calculate the time needed for complete conversion of a particle of oxide at a temperature of 600C and at a pressure of 1atm by neglecting gas film resistance. Take De =0.03cm2/s, the diffusion coefficient for hydrogen penetration. [15] 7. The catalytic reaction A3R is carried out in a packed bed reactor at 3.5atm and 115C. It is desired to treat 1500mol/h pure A to achieve 32% conversion. The following rate-concentration data are available: 8. The following data of the gaseous second order reaction AR are obtained in experimental catalytic packed bed reactor with C10=60mol/m3 and v0=3liter/min.
